Abstract: An apparatus for aligning non-synchronous input data streams received in the apparatus, the apparatus comprising an analog to digital converter arrangement for digitizing the data streams into a plurality of sequences of samples; and a synchronization processing arrangement for generating alignment pulses for each sequence of the plurality of sequences of samples, for arranging each sequence of samples with respect to the alignment pulses for the sequence and for synchronization the delivery of said plurality of sequences of samples to a common processor with respect to the respective alignment pulses. The synchronization processing arrangement may comprise a processing chain for each antenna feed of said plurality of antenna feeds and each processing chain may comprise an alignment pulse generator for generating an alignment pulse for the sequence of samples corresponding to the processing chain. The input data streams may be received by a plurality of antenna feeds.
